Calcium chloride - Wikipedia
Calcium chloride is used in concrete mixes to accelerate the initial setting, but chloride ions lead to corrosion of steel rebar, so it should not be used in reinforced concrete. The anhydrous form of calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete.

13/9/2012· In between the limits, as pH, water content and chloride concentration vary, so too does the corrosion rate of the hot-dip galvanized steel coating. Since most galvanized structural steel has at least 3.9 to 5 mils of zinc coating, estimated service life in the harshest soil is 35 to 50 years and in the less corrosive soil, 75 years or more.
